Why do we look at glaciers on the Tibetan Plateau? _ fresh water storage _ (seasonal) runoff from glaciers _ glaciers as sensitive instruments reflecting climate variability and climate change on different temporal scales: - direct atmospheric forcing of mass balance components (seasonal to annual signal) - indirect, integrative response of glacier volume and geometry (annual to decadal signal) - nonlinear behaviour through tipping points in the glacial system (polythermal glacier!) _ sensitivity analysis of glacier systems allowing for inverse modelling of atmospheric forcing and its variability Christoph Schneider 4/23
